Subject Matter

Instructions for Docker

Content Location

A new section under "add-the-certificate-to-applications" listed here: https://developers.cloudflare.com/cloudflare-one/connections/connect-devices/warp/user-side-certificates/install-cloudflare-cert/#add-the-certificate-to-applications

Additional information

Docker is a widely used technology that by default will not work when TLS inspection is enabled, and require configuration steps to add Cloudflare CA certificate and make it works. As it's very popular, would be nice to have instruction to make the setup work for Docker along the other applications already listed in the page.
Thank you
